When driving my car down the street today, it abruptly stopped in the middle of the street and and engine locked up. I could not shift gears. I could not put my car in neutral. I was literally stuck in the middle of the street with a vehicle that gave me no warning of malfunctioning. This is the 3rd transmission that I have had in this car. It is a 2021 Buick Enclave with just over 12,000 miles.

This vehicle has an auto stop start feature that the dealer refuses to override. The problem is that if you are stopped to make a left turn, the engine stops. When you need to go when there is a break in traffic, there is a hesitation to get going just when you need instant power. Also at stop lights or signs you tend to keep tapping the brake to keep it running resulting in a dangerous situation. Also if you are stopped and forget and get out of the car, it can start up and run into something. I just want the ability to disable this dangerous feature.
